STEATE TRAP.

Application filed December 29, 1924. Serial No. 758,761. I

The invention relates to steam trapsand refers more particularly to means for quickly renewing the valve or valve seator both thereof. Further features of my invention include the provision of a simple and eliicient arrangement for readily replacing the valve or valve seat or both, the arrangement being such that the repair parts are readily available. rlhe invention also includes ,a reversible and rotatable valve carrying member in combination with a reversible and rotatable valve seat disc.

VJhile I have shown my invention applied to a steam trap it shouldrbe understood that it may be usedv and is within the contemplation of my invention, in connection with other devices where renewable valves or valve seats are desired.

lVith these and other objects in view7 the invention resides in the novel features of construction and combination and arrangements of vparts as more fully hereinafter described and claimed.

Referring to the drawings Figure 1 is a sectional elevation showing vone form of my invention applied to a steam trap; y

Figure 2 is a plan of the valve seat disc, and

Figure 3 is a fragmentary elevation showing a modified arrangement of the valve carrying member.

In the drawings, reference character 10 indicates a steam trap of which 11 isthe inlet,

` 12 is the bucket pivoted at 13 to the body portion 14, 15 is the outlet pipe, and 16 is the valve rod pivoted at 17 to the bucket 12, all of which parts may be the usual or any surtable construction.

Secured to the upper part of the cover 21, as by bolts, is a cap 18.

The upper part of the outlet pipe 15 may be formed with projections .19 for maintaining proper valignment of the valve rod 16. The upper end of the valve rod projects into a chamber 2O formed within the cover 21, the

`Arod 16 being preferably formed with a reduced portion 22 adapted to rotatably receive the valve carrying member 23. The latter member comprises a plurality of arms 23a eX- t'ending radially from the axis ofthe rod 16, the outer ends of the arms being formed with oppositely extending valve seat engaging elements or valve points 211 and`25 respectively. The extremities of the arms 23a may be formed with projecting surfaces 2.6 adapted to engage the vertical walls of the chamber 20 for assisting in 4maintaining the valve in proper position. The cover 21 is formed with the upper wall 27 arched to accommodate rotation of the upper valve points 241. A nut 23 serves to hold the valve carrying member 23 fixed to thev rod 16 inany position of rotative adjustment of member 23. Furthermore, by removing the nut 28 the member 23 may be reversed to bring valve points 25 selectively into registry` with the valve seat to be hereinafter described.l

The chamber 20 is. provided with outlet 29 and the passage of steam and fluid therethrough is controlled by a valve seat member 'such as the disc 30 provided with a plurality of ci-rcumferentially arranged valve seats `31 adapted to be selectively brought into alignment with the outlet 29 by reason of a pivotal screw bolt 32 secured to the cover 21. The

disc is also preferably reversible by removing the screw bolt 32 and reversing the disc. 33 indicates the outlet from the cap 18.

The member 23 is adapted to be rotated only on disassembly of the valve member with respect to the steamtrap The arrangement could, of course, be readily modified to permit rotation of the member 23 inthe assembled condition of the parts, but las shown' it is preferred to disassemble the valve member before rotating the same to bring one ofthe valve points into position for operative engagement'with one of the valve seats. f

From the foregoing description, it 'will be apparent thatl have provided means for quickly and conveniently renewing a worn valve point or valve seat or both. Also, by the arrangement including the rotatable valve carrying member, and the rotatable valve disc, a large number of renewable valve points and seats are incorporatedv in the "con- Thisnumber of available renewp struction. able parts is further increased by arranging the valve carrying member and the valve seat disc reversible.' It is therefore, apparentl that any of the valve points may be selectively brought into registration with any of the valve seats, the nut 28 and the screw bolt 32 respectively permitting the selective positioning of these parts. i'

1t is understood that the steam trapmayy operate in the customary manner, the inletll serving jto periodically fill the] bucket 12 which is tilted'on its pivot' 13, causing the valve red 16 to be'inoved downwardly to per-V Inly mit discharge from the bucket 12 upwardly through the outlet pipe l5, chamber 20, outlet 2),valve seat Bl and outlet 83.

Y Referring to Figure 3, I have slioivn a modified construction oi' valve carrying ineinbei'. In this embodiment, the valve rod lli terminates inA a yoke 3l kto which is rotatably pivotally mounted at 22", the vulve carrying member 23 having a plurality of valve points 24e adapted to be. selectively aligned with the valve seats Slol the valve disc 30 Which is Vto a steam trap it is obviousthat it may be used in other devices Wherever renewable valve points or seats are desired. l y

VV'liile it i believed that Jfrom the foregoing description, the nature and advantage of my invention will be readily understood, I desire to have it understood that I do not limit myself to Whatis herein shown and described and that` suoli changes may be resortyed to when desired as fall Within the scope of the claims.
